the unit fully into the mounting position.
Rotate the locking device to the SLIDE position (2), slide the unit along the
DIN-rail to the desired mounting position, and using the connector plugs and
sockets gently attach it to the adjacent unit baseplate.
To prevent damage to the pins, ensure that the baseplate plugs and sockets are
fully aligned as the units interconnect. Do not apply excessive force.
